also important to remember those in need. Every year, the association

features a charity during the December meeting. We ask for donations

and contribute all door monies to the cause. This year, the organization

we will be supporting is A New Direction Beverly Morgan Park (AND),

a grassroots group seeking to help women, men and children who

are victims of domestic violence. A New Direction provides crisis

intervention, safety planning, counseling, education and support as well

as legal advocacy and resources to navigate the legal system to those

in need. So how can you, as members, help? Please bring monetary

donations or gift cards (grocery, gas, clothing stores, Visa, etc.) as your

entry into the event. I thank you in advance for your generous support

and partnership in benefiting this organization.

I would also like to take this time to thank all of our members for

their support in 2018, vendors for their advertising and sponsorship,

engineers for attending events and engagement with our sponsors

and for bringing guests to show off our organization. As a board, we

work hard to provide a variety of events so our vendors can showcase

their products and services and engineers can come network. The

relationships built at these events foster collaboration and provide

endless resources. Thank you for being a part of this growing


I wish you and your families the very best as we enter the holiday

season. I look forward to seeing everyone at the December meeting so

we can toast to a successful 2018.

In Brief

Mold Cleanup Kept Suburban Chicago

School Closed

CALUMET CITY, Ill. (AP) — Officials kept a suburban

Chicago school closed while crews worked to cleanup

mold found inside the building.

Wentworth Junior High School in the southern suburb

of Calumet City was kept closed to facilitate remediation

efforts. The school district also shut down its

elementary and intermediate schools on the scheduled

first day of classes, but opened those buildings the

following day.

District superintendent Troy Paraday said that officials

were taking the matter very seriously and are committed

to giving students a safe learning environment.

U of I Professor to Head Planned

Chicago Innovation Center

CHICAGO (AP) — The University of Illinois has picked

one of its own professors to head an effort to build

and operate a major innovation center in Chicago’s

South Loop.

William H. Sanders has led the engineering department

at the university’s Urbana-Champaign campus

since 2014 and will oversee what’s called the Discovery

Partner’s Institute. The Chicago Tribune reports those

duties will include leading construction of the center,

supervise all faculty and staff hiring and oversee all

new corporate and academic partnerships.

Once it is operating, the center is expected to employ

more than 100 faculty members who will specialize in

research on computing and big data, environment and

water, food and agriculture and health and wellness.

School officials say the center will accommodate more

than 2,000 students a year.

Workers Fixing Bridge Find Note Left

by Crew Who Built Span

ALBANY, Ind. (AP) — Construction workers repairing

a central Indiana bridge discovered a note apparently

left behind by the crew who built it 80 years ago.

The jar shattered but it contained a tattered slip of

paper that reads “List of last crew working on this

bridge,” and includes the names of 17 carpenters,

cement finishers and others it says worked on the span

during 1938 and 1939.

Henry calls it “a neat piece of history” that the town

near Muncie plans to display.

Indiana City Won’t Restart Coal Plant

Despite Relaxed Rules

LOGANSPORT, Ind. (AP) — A northern Indiana city’s

coal-burning power plant won’t be reopening despite

the Trump administration’s plan to relax restrictions on

greenhouse gas emissions from such facilities.

Logansport Municipal Utilities shut down its plant in

early 2016 after deciding it couldn’t afford updates

needed to meet rules established under former President

Barack Obama.

City utilities Superintendent Paul Hartman tells the

Pharos-Tribune that a coal-fired power plant generally

can’t be restarted after several months out of action.

The plant generated about 30 percent of the Logansport

utility’s electricity. Duke Energy has provided

it all since the plant’s closure. Some equipment inside

the former plant has been sold for scrap.

Energy Department Says Wind Power

Projects Continue in US

OKLAHOMA CITY (AP) — The U.S. Department of

Energy reports that the continued construction of

wind-power generating stations is bringing down both

the cost of building the installations and the price for

wind-generated electricity.

The report in August shows Texas leads the nation

with 22 gigawatts of wind capacity, followed by Oklahoma,

Iowa, California and Kansas with each at more

than 5,000 megawatts.

A gigawatt is 1 billion watts of power; a megawatt is 1

million watts.

Man Accused of Selling Historic Bridge

Metal Seeks Dismissal

HAMMOND, Ind. (AP) — A northwestern Indiana

scrap-metal dealer accused of demolishing a historic

bridge and selling the metal is seeking to have the

federal charge he faces dismissed.

Kenneth Morrison argues in a motion filed Aug. 27 in

federal court in Hammond that questions about who

owned the bridge warrant his indictment being tossed.

Morrison operates T&K Metals in Whiting. He was

charged in 2017 with interstate transportation of

stolen property for allegedly taking metal from a

long-unused 1910 railroad drawbridge and selling it to

an Illinois scrapyard for $18,000.

The Post-Tribune reports Morrison’s attorney says

investigators told a grand jury the city of Hammond

“conclusively” owned the bridge, but that public

records and correspondence between the city and a

railroad company showed they couldn’t say for certain

who had the bridge’s deed.

Illinois Football Program Gets Millions

to Build New Center

CHAMPAIGN, Ill. (AP) — The University of Illinois Foundation

is getting a $20 million donation, including $15

million for the Fighting Illini Football Performance


The money is coming from the H.D. Smith Foundation.

Henry Dale Smith started H.D. Smith, a medical wholesale

company based in Springfield, Ill.

Chris and Dale Smith say they’re honoring their late

father and mother Betty and the couple’s passion for

Illinois football.

The Smith Foundation’s gift also includes $3 million for

athletes to return and complete their degrees.

Hammond Schools to Provide Bottled

Water at 7 Buildings

HAMMOND, Ind. (AP) — Hammond’s school superintendent

says bottled water will be provided to students

in buildings where elevated lead levels were

found in drinking water.

Superintendent Walter Watkins said in an email to

staff on Aug. 30 that seven buildings, including six

schools, registered lead levels above the recommended

Environmental Protection Agency threshold when

tested on Aug. 9-13.

The Post Tribune reports the high lead levels were

found in 19 fountains at the six schools. Watkins says

those fountains were taken out of service until further

testing is done. Bottled water will be provided at each


Opening of Pedestrian Bridge Delayed

for Additional Testing

FORT WAYNE, Ind. (AP) — The opening of a pedestrian

bridge that will link two college campuses in Fort

Wayne has been pushed back by additional testing of

the span.

The Parker Cole Crossing was initially set to open in

June, spanning a busy roadway to link Purdue University

Fort Wayne and Ivy Tech Community College.

But the Indiana Department of Transportation added

additional testing to ensure the $4.5 million bridge

meets design and construction standards.

Greg Justice is Purdue Fort Wayne’s executive director

of facilities management. He tells The Journal Gazette

that the added testing is primarily responsible for the

delayed opening of the bridge, which about 1,000

students are expected to use daily.

Albany Town Marshal Shannon Henry says workers

were using a jackhammer to break up concrete on

Bridge 701 last week when a glass jar fell out.

The report says wind energy provided 6.3 percent of

the nation’s electricity supply in 2017.

The average price for wind power has fallen from 7

The Henry Dale and Betty Smith Football Center

will be a 107,000-square-foot facility with space for

AKF’s Mark Richter to Chair World’s

Foremost Tall Buildings Design Award


Hidden Emergency Lighting Preserves

Building Aesthetics While Meeting Code

Richter’s 26-year career includes the design of iconic New

York City buildings such as One57, Central Park Tower, and

520 West 28th, the new luxury condominium along the Highline

designed in collaboration with Pritzker Prize-winning

architect Zaha Hadid. 520 West 28th won AKF an American

Council of Engineering Companies New York State Diamond

Award for engineering excellence. Mark also added that the

CTBUH gathering is the perfect venue to celebrate professionals

whose passion is engineering healthy, sustainable tall


“As buildings across the globe continue to get taller and taller,

a comprehensive approach to sustainability is critical. AKF

has always delivered design enhancements that are above

energy code, mindful of the surrounding environment, and

conscious of their energy impact. I look forward to joining

other jurists who share these values.”

AKF’s Mark Richter will serve as 2019 Jury Chair for the CTBUH Annual

Awards’ MEP Engineering Panel.

NEW YORK (GLOBE NEWSWIRE) — AKF, a global leader in

engineering, technology, design, consulting and commissioning,

is excited to announce that Partner Mark Richter, PE has

been appointed by the Council on Tall Buildings and Urban

Habitat (CTBUH) to serve as 2019 Jury Chair on the MEP Engineering

panel for the CTBUH Annual Awards.

“For nearly 50 years, CTBUH has been a leading authority on

tall building and urban design trends,” said Richter. “And

today, as technology continues to change the landscape for

MEP professionals around the globe, CTBUH continues to set

the standard for the construction and design of next-generation

buildings. I am honored to chair the MEP Jury.”

Richter, who has earned praise for his expertise in the

planning and design of high-rise and mixed-use properties,

noted that to date AKF has been instrumental in the design

and commissioning of more than 30 high-rise and super-tall

structures around the globe. This includes work on four of

Mexico’s five tallest buildings, as well as Three Sixty West in

Mumbai, which will be India’s tallest building upon construction


Many of Isolite’s architectural emergency lighting solutions are virtually invisible during normal lighting conditions, eliminating unattractive surface mounted

emergency lights.

While emergency lighting is critical to life safety and must

function to code, no one wants to see the devices ruin the

aesthetics of a building’s interiors. So industry professionals

are increasingly keeping the lights hidden or camouflaged

until needed to ensure it artfully blends in with its surroundings.

“From the standpoint of interior architectural aesthetics, traditional

wall or ceiling-mounted emergency lighting systems

can be sort of an eyesore that establishments with a more

refined look want to eliminate because it can take away

from the architectural experience,” says John Decker, IALD of

Lighting Design Studio, a multi-disciplinary firm. The company

has completed lighting projects for a variety of commercial

spaces including resort hotels, spas, casinos, restaurants,

retail, and office spaces.

Now an innovative option, fixtures completely hidden

behind closed-door panels on walls or ceilings, is helping to

meet emergency lighting code. Only in the case of emergency

or power outage do the doors open and the emergency

lights emerge to ensure sufficient light along the path of

egress, as mandated by the NFPA and International Building

Code (IBC). For even greater discretion, the panels can be

painted, wallpapered over, and placed in locations out of the

line of sight to make them completely inconspicuous.

Enhancing Aesthetics and Ensuring Safety

Design professionals often meticulously plan the aesthetics

of various building elements including style, form, and ma-

terials in a wide range of structures. This can involve upscale

hotels, resorts, restaurants, retail centers, office buildings,

and concert halls as well as historic courthouses, museums,

city halls, state and federal buildings.

A challenge, however, occurs when urgent project timelines

lead to unfortunate compromises in building aesthetics, often

in the area of emergency lighting, at the last minute.

“When building owners and end users pay for architectural

services, they may have a wonderful structure with everything

considered in the space – until the end of the project

when ill-considered, utilitarian, even ugly, emergency lighting

is installed to provide light for emergency egress,” says


“In nicer hospitality, entertainment, office, and service settings

with refined interiors –like hotels, resorts, restaurants,

spas, casinos, museums, historic districts, and themed amusement

parks – foreign looking emergency lighting fixtures

mounted to the walls or ceiling can look really out of place,”

he adds.

While there are many emergency lighting approaches available

that will sufficiently provide one foot candle of illumination

along the path of egress as specified by the NFPA,

these options typically begin with deciding on the type of

power source that will be used in the event of a power outage.

Often, existing architectural lights are incorporated if possible,

powered by centralized inverters or generators. However,

when that is not sufficient, dedicated battery powered

emergency lights may be required, but these can be obtrusive

and unattractive.

“If the engineer proposes to put ugly, ‘bug-eye’ emergency

lights in a beautiful interior space, we try to find aesthetic

solutions that still meet the code requirement of providing

enough egress lighting for emergency situations – while

maintaining the beauty of that space,” says Decker, who is a

trained architect.

“Bug-eye” is the colorful term used to describe typical

emergency lighting that surface mounts on the wall with a

battery box under two lamps that resemble a bug’s eyes.

Decker says there are superior methods for hiding, or concealing,

emergency lighting.

The first method is to utilize a backup battery hidden in the

housing of a lighting fixture, such as a recessed downlight or

suspended linear luminaire. In the event of a power failure,

the battery will then supply emergency lighting for a designated

amount of time as determined by code.

However, Decker points out another alternative. He points

to Isolite, a manufacturer of specification-grade emergency

lighting products. The company offers the Genie, along with

a more compact version called the Mini Genie, that remain

fully recessed behind two flat panel doors installed in the

ceiling or walls until needed.

“With the Genie and Mini Genie, you have a concealed look

architecturally, but under normal loss of power the battery

kicks in, the doors open, and the lamps pop out to light the

way,” says Decker.

“The recessed solution lends itself to maintaining the integrity

of the architectural interior space, so it works functionally

and aesthetically,” he adds.

While having emergency lights emerge from door panels

when needed keeps them out of the way, lighting professionals

like Decker also value the ability to camouflage them

as well.

With both of the units, the flat panel doors lay flush with the

trim and mounting surface, and exterior trim can be painted

or wall-papered to match any color or decor so as to blend in

with the architecture.

Because these emergency lights are fully self-contained and

can be recessed into walls or ceilings, they are virtually invisible

during normal lighting conditions, and thus eliminate

unsightly, surface mounted emergency lights and battery


While this approach can enhance the aesthetics of new

builds and retrofits, it is particularly helpful in preserving the

“look and feel” of historic buildings, which still must accommodate

life safety and security needs, as well as update

building systems appropriately.

Such implementation strikes a balance between retaining

original building features and accommodating new technologies

and equipment.

In fact, the Mini, which can wall mount with a total depth of

3.5”, is also well suited for shallow plenum applications, the

narrow space between the structural ceiling and drop-down

ceiling used for HVAC air circulation.

The company also offers recessed LED emergency lighting

mounted 18” above the floor. The product directs light to

the floor to more effectively illuminate the path of egress

than traditional ceiling or wall mounted emergency lights.

“Lighting the path of egress from a lower vantage point

makes sense in situations where there is a fire because all the

smoke rises and [if it were higher] it could block some of the

light,” says Decker.

With such new tools to make emergency lighting less conspicuous,

building design professionals can now preserve

elegant, architectural quality aesthetics while meeting emergency

lighting and life safety codes.

“Wherever aesthetics are valued, concealing emergency

lighting should be an option,” concludes Decker.

“When the Isolite products are fully recessed and the panels

are painted or wallpapered to match their surroundings, you

really cannot see them unless you are specifically looking,”

says Decker.

For more information, contact Isolite at 31 Waterloo Avenue,

Berwyn, PA 19312; call 800-888-5483; or visit them on the

web at www.isolite.com

According to Decker, the design and engineering team

utilized this approach for emergency lighting in the themed,

Camp Jurassic caves at Universal’s Islands of Adventure in


“We used a Genie product, and it was painted out so you

really couldn’t see it unless you were looking for it,” he says.

“It maintained the integrity of the aesthetics.”

Building Up With Precast Concrete


BEAUSEJOUR, Manitoba, Can. — Builder Syed Bokhari passionately

believes in creating durable, energy-efficient housing

for seniors. That dedicated focus has led him to explore

creative construction practices — including the use of precast

concrete panels from Superior Walls by Magnis.

“I first saw a Superior Walls basement foundation two years

ago and thought it was a great way to build,” says Bokhari,

president of Noble Builders in Winnipeg, Manitoba. “Then I

went and viewed a wide variety of different Superior Walls

basements and decided this was the product I wanted to use.

The speed of installation truly accelerates the work on site,

plus the energy-efficiency features are an asset in our area.”

Working with a design created by T-Square Techniques, Inc.,

Noble Builders is now approaching the final stages of construction

on a three-story seniors residence at 51 Kaatz Drive

in Beausejour, Manitoba. The team decided to “build up”

with precast concrete panels and created the entire exterior

of the building — plus the interior elevator shaft — with

custom panels supplied by Superior Walls.

“We selected the precast wall product primarily for its speed

in erecting and enclosing the building structure,” says Brian

L. Mansky, principal owner and chief designer at T-Square

Techniques, Inc. in Winnipeg. “This is technically a far superior

building envelope system as compared to standard wood

frame construction. While this is our first time specifying

Superior Walls for a project, we’ve been so impressed with

the product that we’re considering it for other projects.”

Reliable Concrete Walls

The 35-unit independent living residence for seniors at 51

Kaatz Drive incorporates Superior Walls Xi Plus panels into

the building envelope.

“The exterior walls include 2,400 linear feet of eight-foot tall

Xi Plus panels, and then there’s an additional 120 linear feet

of 10-foot tall Xi Plus panels for the elevator shaft,” says Ray

Wentz, special projects manager at Superior Walls by Magnis.

“This is the first multi-story, above-ground application of our

products in this area.

Precast concrete panels offer many advantages, including durability, energy efficiency and ease of installation.

“The advantages of using precast concrete panels in this type

of building construction are amazing. Each wall panel is custom

made to the exact specifications of the plan. The panels

install quickly and resist mold, rot, fire and noise. These are

incredible features for a senior living facility.”

Superior Walls Xi Plus wall panels (Canadian markets) feature

steel reinforced concrete and 5″ Neopor® Rigid Thermal

Insulation to create a barrier against sidewall water penetration.

The panels are custom designed and constructed in

a factory-controlled setting. Unique features of the Xi Plus

wall panels include:

• 5,000+ PSI concrete

• Steel-reinforced top bond beams, concrete studs and footer


• Horizontal steel rebar inside top and bottom beams

• Vertical steel rebar inside each stud

• Galvanized steel stud facing ready for drywall finishing

• Insulated corners, studs and bond beams

• A four-inch insulated footer beam

• 5″ Neopor Rigid Thermal Insulation to provide an insulation

value of R-24

• Four insulated access holes are included in each standard

stud to provide greater ease in wiring and plumbing.

(Continued on page 16)

Bokhari agrees that the benefits of the concrete panels for

the project make them a winner for the senior living facility.

“We had the shell up on the structure in less than four

months, which is impossible to achieve with poured concrete,

concrete blocks or traditional wood frame construction,” says


The “shell” of this structure includes a broom finish to the

concrete exterior, providing a scratch coat for acrylic stucco

and cultured stone accents. The finish can also be painted.

“This is a new way of building,” says Bokhari. “It’s faster

and more reliable than past building methods. I can see us

working on many projects in the future with Superior Walls

foundations and above grade applications.”

Interior Elevator Shaft

One of the most beneficial aspects of using precast concrete

panels on the 51 Kaatz Drive project came in the construction

of the elevator shaft.

While concrete block construction has been the industry

standard for elevator shafts in years past, the fast installation

of Superior Walls speeds up the construction schedule. As

well, these walls remain non-combustible and heat transfer is

minimized as they are insulated panels.

“A concrete stairwell or elevator shaft can give building

occupants additional time to escape from a burning structure

because the material resists the movement of the fire,” says

Wentz. “A zone delineated by concrete within a building can

provide escape routes during a fire by maintaining structural

integrity and allowing people to get away from the building.

At the same time, this allows firefighters to more safely enter

the structure and fight the fire from multiple locations and


During the construction of 51 Kaatz Drive, the Superior Walls

precast concrete panels were placed in the elevator shaft

with the concrete side faced inward and with a fireguard

facing outside. The exterior facing wall was covered with

Wisconsin Man Repairs Museum’s

Flood-Damaged Vehicles

By Barry Adams | Wisconsin State Journal

SPRINGFIELD, Wis. (AP) — Chris Beebe’s automotive resume is


For more than 45 years he founded, owned and operated

Foreign Car Specialists in Madison, has raced a wide range

of vehicles, worked as a racing instructor, written for automotive

publications and developed hybrid vehicles, including

the prototype for the Chevy Volt. From 2008 to 2011, he and

a team even competed for the Automotive X-Prize.

Water reached the bottom of the windows of the museum’s

historic buildings and filled not only the passenger compartments

of the cars but also the engines, lights and any other

cavity below the waterline. And the water was far from

clean. It contained not only mud, debris and likely sewage,

but also oil from the vehicles. So when the water receded,

every German Messerschmitt and Heinkel Bubblecar, East

German Trabant and English Bond were not only soaked but

left covered in a film of oil.

Beebe’s latest effort is testing all of his skills, patience and his

73-year-old knees and back.

Since late August, Beebe has been self-sequestered in a

storage shed on a farm north of Middleton and just west of

Ashton where he is working to dry out, repair and restart 15

cars and 13 motorcycles from the Midwest Microcar Museum

in Mazomanie that were damaged in late August when

torrential rains flooded the village.

Even the Amphicar, a car that doubles as a boat, was damaged.

It failed to float and the seals on its doors were compromised,

which flooded the interior.

“I’ve seen everything here but I haven’t seen the internals of

many of these so it’s been a real eye-opening experience,”

Beebe told the Wisconsin State Journal as he took a break

from cleaning the starter for a French-made Renault 4CV.

“You just have to be sensitive as to what water got into

what. It’s really ugly, but at least it’s not salt water, which is

much more corrosive.”

The water quickly receded and the vehicles were pulled from

the six inches of sludge that covered the museum floors before

they were hauled in multiple trips by trailer 22 miles to

the farm shed. But the restoration efforts are complicated by

the design of the vehicles.

The motorcycles are fairly straightforward, but the microcars

have limited access to the engine compartments, so Beebe

wears kneepads and a headlamp. In some cases, he has to

crawl through interiors to reach small openings in the back

of a vehicle to where the engine is located.

And the engines themselves, in many cases, are glorified

lawnmower engines. That means there are no drain plugs, so

motors need to be tilted to drain, which really isn’t an option

since they’re installed in a car body. Putting the vehicles on

a lift doesn’t work because of their odd designs, although

Beebe thought about lifting the cars and then attaching

straps and inverting the vehicles. But because of the logistics,

he has instead chosen to drill into the engines small drain

holes that are then threaded and plugged once the water is


Humidifiers and fans have been constantly running in the

shop and at the museum buildings, while the seats and other

interior coverings have been removed and are now laid out

on the floor of the shed until they can be repaired and put

back into the vehicles by Vic’s Auto Upholstery in DeForest.

Tags with detailed notes have been attached to each car and

motorcycle indicating what has been done so far in the restoration


“He’s a gift from God,” Carlo Krause, a longtime car collector

who opened the museum in 2015, said of Beebe. “You’d

never find another guy around here that even comes close to

what this guy is doing. I nearly kiss the guy every time I see


Krause, 78, bolstered his car-collecting hobby after health

problems forced him to retire about 20 years ago from his

business designing and selling components for automated

processing machinery. His father, who also was an electrical

engineer, started the business in the basement of his home

in Lake Geneva. Krause, who lives just outside of Middleton,

and his son, Sven, got the idea for the museum after some

of their microcars were showcased at a three-day car show

at Discovery World in Milwaukee about five years ago. The

exhibit drew more than 4,000 people.

The first museum building was purchased by Krause in 2015

and is located in the former blacksmith shop of John Parman,

who built the facility across the street from his 1864 brick

home that still stands across the street. All of the vehicles

on the ground floor of the building were damaged but 10

microcars on the second floor remain in place and were unscathed.

The remainder of the collection is about 25 yards to

the west in the Mazomanie’s town hall, constructed in 1878

but now owned by the village. Krause began leasing space

in the building in 2017, made improvements to the structure

and had cars and motorcycles on the ground floor and about

15 motorcycles on the second floor.

Most of the 30 microcars in Krause’s free museum are from

the 1950s and 1960s. He even has a few bicycles with motors

built into their rear wheels. The museum, where damages

are estimated at more than $300,000, likely won’t reopen

until next spring. Meanwhile, dumpsters and construction

trailers dot the village where dozens of homes and commer-

cial properties sustained flood damage.

“If you don’t have anything running and you ever want

to sell it, they’re worthless,” Ingrid Krause, Carlo Krause’s

wife, said during a walk through the damaged buildings in

Mazomanie. “What’s sad is that everything was basically in

original condition.”

Microcars became popular modes of cheap transportation

after World War II and were built by manufacturers across

Europe, including by companies that had been making military

equipment during the war. Most of the early microcars

traveled no faster than 50 mph with 200cc to 250cc, one-cylinder

engines, while later models sported slightly larger

motors that increased speeds to more than 70 mph.

Beebe had visited the Microcar Museum just a week prior

to the flood and reached out to Carlo Krause shortly after

learning of the museum’s plight. Just days later he was at

Krause’s farm shed, which holds other cars in Krause’s collection.

Only now it resembles a working museum of repair.

Doors and small hoods to the vehicles are propped open and

even two months after the flood, dehumidifiers and fans are

constantly running in an effort to draw out moisture from

the vehicles.

Beebe and his assistant, Doug Heideman, who worked at

Foreign Car Specialists prior to its closing in 2014, have been

using rags and cleaning solutions to remove mud and oil but

have also flushed engine compartments and chain cases with

a mixture of isopropyl alcohol and WD-40. Wiring has been

repaired and generators, carburetors and anything else that

holds water have been removed (if possible) and dried.

“There was water in everything,” Beebe said. “It’s taken a lot

to get mechanical stuff back working again.”

But the effort to make the microcars whole again has involved

some sleuthing by Beebe, since there are few resources

in the U.S. for repairing the tiny vehicles. So when Beebe

had a question about how much oil was held in the chain

case of a Messerschmitt, he went to a mud-stained membership

publication of a Messerschmitt club that was salvaged

from the floodwaters. Beebe was able to find phone numbers

for two of the four people in the U.S. listed in the 1978

booklet. One of them, from Florida, called back.

“He was so nice. It was really great,” Beebe said. “There are

no manuals for this stuff.”

that it has issued permits to Poly Met Mining Inc. for a planned copper-nickel mine at the site. (AP Photo/Jim Mone, File)

Divisive Minnesota Mine Wins Permits,

But Faces Challenges By Jeff Baenen

MINNEAPOLIS (AP) — Minnesota regulators on Thursday,

Nov. 1, granted key permits to the long-planned PolyMet

copper-mining project that’s opposed by environmentalists

who fear it could someday foul waters, including Lake Superior.

The state Department of Natural Resources issued permits to

PolyMet Mining Inc. for the company’s proposed NorthMet

project in northeastern Minnesota. The project still needs

permits from other agencies, and likely faces court challenges.

“No project in the history of Minnesota has been more

thoroughly evaluated,” DNR Commissioner Tom Landwehr

said in announcing approval of permits for the project, first

proposed in 2004.

Environmentalists have opposed the mine for fear it could

pollute pristine waters and destroy habitat for gray wolves

and Canada lynx. The project would be located near tributaries

feeding the St. Louis River, 175 river miles upstream from

Lake Superior.

Duluth for Clean Water said the proposed mine “would

create permanent, toxic pollution in the headwaters of Lake

Superior, putting our communities and lives in constant

“The massive open-pit mine would destroy huge swaths of

the Superior National Forest and significantly increase annual

CO2 emissions in Minnesota at the worst possible time,” the

group said.

PolyMet contends it can operate the proposed mine near

Hoyt Lakes and Babbitt without harming the environment

while creating hundreds of badly needed jobs on Minnesota’s

Iron Range.

“We look forward to building and operating a modern mine

and developing the materials that sustain and enhance our

modern world,” PolyMet President and CEO Jon Cherry said

in a news release. “Responsibly developing these strategic

minerals in compliance with these permits while protecting

Minnesota’s natural resources is our top priority as we move


Paula Maccabee, an attorney for environmental group WaterLegacy,

said environmentalists will likely appeal if permits

are granted, or they could request that the DNR reconsider

its decision.

The agency issued a permit to mine, six water appropriation

permits, two dam safety permits, a public waters work

permit and an endangered species takings permit for the

project. The permit to mine includes a financial assurance

plan — designed to provide enough money so the DNR can

reclaim and close the mine and plant site in case PolyMet

does not — and a wetland replacement plan. The project still

requires water and air quality permits from the Minnesota

Pollution Control Agency and a wetlands permit from the

U.S. Army Corps of Engineers.

Landwehr said the DNR is “confident that the project can be

built, operated, and reclaimed in compliance with Minnesota’s

rigorous environmental standards.”

“Yes, there will be an environmental impact,” Landwehr told

reporters. “Our job is to ensure those environmental impacts

are within state standards, and whenever required, they are


Maccabee and other environmentalists questioned why the

DNR did not conduct a contested case hearing for an independent

review before issuing the permits. But Landwehr

said the project did not meet the standards under state law

for such a trial-like hearing.

“These permits should be reviewed by an independent

administrative law judge to establish the facts before permit

decisions are made,” Kathryn Hoffman, chief executive of

the Minnesota Center for Environmental Advocacy, said in a

statement, noting that such hearings are routine for pipelines

and power plants. “It is special treatment for PolyMet

to skip this vital step for the first copper-nickel mine to apply

for permits in Minnesota.”

Minnesota Republican legislative leaders hailed the DNR’s


“This new mine will create many good-paying jobs in Northeastern

Minnesota and provide a real boost to the state’s

economy,” House Speaker Kurt Daudt, a Republican from

Crown, said in a statement.

The project would cost an estimated $945 million to construct.

PolyMet said site preparation and rehabilitation of the

former LTV Steel plant for a copper-nickel processing plant

will continue through the winter and early spring. The company

said the bulk of work is expected to start in the 2019

construction season and last about 24 to 30 months.

Forging Ahead with Advanced HDPE

Cooling Towers

HDPE Cooling Towers from Delta Cooling are impervious to corrosive

environments, require less downtime for repair or replacement, and lower

amounts of water treatment chemicals.

The forging industry has achieved an impressive place in the

North American industrial economy by producing components

with unique benefits that are difficult to duplicate.

Forging, a manufacturing process of shaping metal by applying

a variety of powerful compressive forces to it, is known

for producing parts that feature excellent fracture toughness,

ductility, as wells as both impact- and fatigue-strength.

However, delivering on those attributes also requires dealing

with the extremely high heat generated during the forging

process, which can reach up to 1,150 degrees C (2,102 F).

For Patriot Forge, a Canadian supplier of custom open die

and rolled ring forgings, controlling those high temperature

hinges on dependable cooling tower technology.

Frequently used for industrial applications such as refineries,

metal foundries and manufacturing plants, cooling towers

remove heat from cooling system water and exhaust it into

the atmosphere.

Needing an Advanced Solution

With plants in Branford and Paris, Ontario, Patriot Forge

produces products in a variety of materials ranging from

carbon, alloy, stainless steel, nickel-based alloys and aluminum.

Producing for demanding industries such as power

generation, petrochemical, heavy-equipment manufacturers,

military and aerospace requires consistent quality, including

the vital hardness characteristics of forgings ranging from 5

lbs. to 50 tons.

According to Derek Hynes, Senior Mechanical Engineer at

Patriot Forge, three years ago, the company decided to begin

the process up replacing its aging, multi-use cooling tower,

located at Building One of its Branford plant.

“The tower we were replacing was a traditional steel model

that was rotting out,” Hynes explains. “Also, metal models

tend to rust and corrode, which usually leads to plugging the

water flow — and that can interfere with cooling capacity.”

This cooling tower is used to expel heat from the Building

parts are submerged in water or polymer baths in order to

Hynes and his team took the time to investigate what other

cooling tower design options were available that could

provide reliable, trouble-free operation for a longer period

of time.

The team ultimately chose a cooling tower constructed on

HDPE (high-density polyethylene) manufactured by Delta

Cooling Towers (www.deltacooling.com), the company that

originally developed the engineered plastic technology.

HDPE cooling towers are impervious to corrosive environments,

and require lower amounts of expensive water

treatment chemicals as well as less downtime for repair or

replacement. The same manufacturer also offers models with

energy-saving features such as direct drive fan motors that

can drastically reduce electricity costs.

“We saw that this was a polymer-based tower that was

UV-protected, and included a 20-year warranty, so we were

convinced that it would offer long-term dependable service,”

Hynes says.

Supporting Multiple Systems

After the initial HDPE tower was successfully installed and

exceeded expectations, Patriot Forge decided to acquire a

second HDPE cooling tower to support hydraulic cooling for

their new 5,000-ton hydraulic press, rail-bound manipulator,

and hydraulic ring roller.

You will be able to register on your phone or other device,

the Building One,” explains Hynes. “This included cooling the

water that flowed through a heat exchanger used to draw

heat off the hydraulic systems of three large pieces of production

equipment, including the 5,000-ton press that plays

a primary role in the forging processes of the plant.”

“Essentially, all three machines are cycling the water that

flows through their hot hydraulic heat exchangers and then

through this cooling tower. This enables us to keep the hydraulic

fluids at a stable 110 degrees (F).”

Extending the Benefits

Then earlier this year, Patriot Forge acquired an additional

twin cell HDPE cooling tower to help cool the quench tanks

that are part of the company’s heat treat system in Building


“Both of the quench tanks are 105,000 gallons, and we use

the cooling towers to help maintain a heat level of approximately

100 degrees (F)”, Hynes says.

The cooling towers that Patriot Forge selected for this building

were the same design as the one selected as a replacement

in Building One, Delta TM Series Induced Draft models.

One of the unique benefits of the TM Series towers is the

ability to configure them in combination of up to six units

with cooling capacity from 250 to 2,500 cooling tons. This

modular design gives companies the opportunity to conve-

niently add cooling towers as their processing grows. The

new, cooling towers installed at Building Two are installed in

a two-cell configuration with combined cooling capacity of

836 cooling tons.

“We decided on this size and configuration because the

quench tanks in Building Two are much larger,” says Hynes.

“So, there is a lot more water you have to process through

the towers.”

He notes that installation of the factory-assembled cooling

towers was relatively easy. “The HDPE plastic towers are

lighter, so we were able to use a smaller crane to install

them, which was much more convenient than having to deal

with larger, bulkier cranes.”

Hynes says the towers feature vibration sensors on all fans,

which eliminates the need to climb the towers in order to

check out the operating performance of the fans, a benefit

that Hynes feels is particularly appealing because one of the

towers tops out at a daunting 65 ft. — “a long way up.”

JUNEAU, Alaska (AP) — The state is offering safe drinking

water to households in a southeast Alaska town after a toxic

substance was discovered in groundwater.

A dozen private wells in Gustavus qualified to receive

shipped-in jugs of water from the state following the discovery

of a chemical compound known as PFAS, Alaska’s Energy

The substance is found in foam used to suppress oil fires. It

can seep into the ground and cause contamination.

The Centers for Disease Control and Prevention released a

The state Department of Transportation tested wells over the

summer near the Gustavus airport.

Gustavus resident Kelly McLaughlin said she learned of the

testing and persuaded the state to test her well. The results

last month showed the well contained twice as much of the

contaminant as the federal government advises for health.

“You don’t think the water you’ve been drinking and assume

is safe is poison,” McLaughlin said. “That’s not a thought

that crossed my mind ever. I wasn’t prepared for the results

to be that bad.”

The state Department of Transportation plans to bring in an

engineer to develop some long-term solutions.

Gustavus is a city of 550 on the north shore of Icy Passage.

The city is 48 miles (77 kilometers) northwest of Juneau. It

is surrounded by Glacier Bay National Park and Preserve on

three sides.

“This was nobody’s fault. As far as I know, nobody knew how

bad these chemicals were,” McLaughlin said. “Nobody knew

how far they would travel. The DOT did not intentionally

poison the people in Gustavus. But it happened.”

Canadian Firm Seeks Arkansas Pilot

Plant to Extract Lithium By Kyle Massey

EL DORADO, Ark. (AP) — Standard Lithium Ltd., the Canadian

company with big plans to tap south Arkansas’ underground

brine stream to extract battery-grade lithium, is

ramping up testing at a pilot crystallization plant in British

Columbia and gaining provisional approval for a pilot extraction

operation west of El Dorado that could be in place

as early as late February.

Standard, of Vancouver, has completed a plant to test its proprietary

selective crystallization process, designed to refine

battery-quality lithium from a solution extracted from brine,

in partnership with Saltworks Technologies Inc. of Richmond,

British Columbia.

The technology in the pilot plant, if successful, could end up

refining extracts pulled from South Arkansas brine, which

was found to hold strong concentration of lithium carbonate

in tests of saltwater from two previously drilled oil and gas

wells in south Arkansas.

Lithium, a valuable element used in everything from cellphone

and laptop batteries to the systems of electric automobiles,

could be a boon for Arkansas’ economy if the publicly

traded Canadian company, which has partnered in brine

leases near El Dorado and Magnolia, can prove its ability to

refine battery-grade lithium at an industrial scale.

The prototype pilot plant, which is undergoing commissioning

for operation now, will be operated initially at Saltworks

Technologies’ Richmond facility. Standard Lithium CEO

Robert Mintak said the ultimate goal is to extract the lithium

and then refine it, all in Arkansas.

He added that the Arkansas Oil & Gas Commission is giving

his company a chance to prove its process by operating the

pilot extraction plant with a waiver.

“The purpose is to prove that we can extract lithium with our

selective extraction plan, and then produce battery-grade

material in Arkansas,” Mintak told Arkansas Business in

a recent telephone conversation. “The purpose is to have

everything in Arkansas,” with the pilot extraction technology

in place in the first half of 2019.

“That plant is going to be moved to Arkansas probably

in late February or early March,” Mintak said. “That’s the

extraction pilot plant. The pilot plant in Richmond, on the

other hand, is a plant that converts the extracted lithium

solution into a final battery material. We’ve developed our

own process to crystallize lithium carbonate, and we feel our

own process may be an improvement, but we’re going to be

working with some other industry partners that have crystallizers

in use around the world. We’ll be testing our own

process along with others.”

Saltworks CEO and chief engineer Ben Sparrow said in a

statement that if Standard Lithium likes the results it sees at

the pilot plant in Canada, “we are ready to rapidly deliver a

mobile fully continuous plant and support Standard Lithium

to commercialize this high-potential technology.”

Mintak has cited Arkansas’ regulatory environment, as well

as its vast supply of mineral-dense brine, as factors that led

Standard Lithium to Arkansas.

“We had a meeting with the Oil & Gas Commission a week

ago and gave a presentation to proceed with a waiver,”

Mintak said in early November. “There is not a royalty set as

yet for lithium in Arkansas, so they’re allowing us to prove

the extraction process works as we operate the pilot plant.

Then as we get data on that we’ll start working with them

on the royalty regime.”

Standard Lithium is listed on Canada’s TSC Venture exchange

under the trading symbol SLL and on the OTCQX under the

symbol STLHF. It is also traded in Europe on the Frankfurt

Stock Exchange.

Officials: Saline County Dam on Verge

of Collapse

HENSLEY, Ark. (AP) — A dam at a central Arkansas lake has

many safety issues that indicate a lack of maintenance and

could cause the structure to collapse, according to state


Arkansas Natural Resources Commission engineer Stephen

Smedley inspected the Lake Sandy dam this year and identified

needed repairs that could cost at least a half million

dollars, the Arkansas Democrat-Gazette reported.

The commission warned nearby homeowners of issues that

could cause the dam to break, emptying the Saline County


“The internal erosion and voids could cause the dam to collapse,”

a letter to residents stated. “The many slides, slumps,

erosion channels, large trees, rodent activity and animal

burrows on the upstream and downstream slope are very

concerning and indicate a lack of maintenance.”

Property owners worry they’ll be liable for damages if the

unregulated dam fails.

The Lake Sandy Property Owners Association acquired the

dam in 1992 and is responsible for its maintenance. The

association had its last meeting in the mid- to late-1990s, and

residents believe that’s when dam maintenance stopped.

If dues had been collected and used to maintain the dam,

some of the structure’s larger problems could’ve been prevented,

Smedley said.

But Mike Oglesby, who lives in a camper by the lake, estimated

that residents haven’t paid dues to the association for at

least 20 years.

Oglesby didn’t know anything about the dam until this year,

and neither did state dam safety officials. Arkansas has data

on 410 regulated dams and nearly 900 more for informational

purposes, but no documentation on Lake Sandy. The Lake

Sandy dam and its ownership aren’t known to the National

Inventory of Dams, either.

“It’s not a matter that the dam will break,” Oglesby said. “It’s

when it will break.”

Tests Find Contamination in

Indianapolis Suburb

FRANKLIN, Ind. (AP) — New test results confirm that groundwater

and sewer vapors in an Indianapolis suburb have

cancer-causing chemicals at levels that exceed the Indiana

environmental agency’s safe limits.

Environmental firm EnviroForensics found high levels of

trichloroethylene and tetrachloroethylene in Franklin, The

Indianapolis Star reported.

TCE and PCE are found in household items, such as cleaning

solutions, but can have harmful health impacts in high concentrations,

according to the Centers for Disease Control and


The U.S. Environmental Protection Agency told city officials

that it’s monitoring the site formerly used by Amphenol, an

electronics manufacturer. Franklin Mayor Steve Barnett said

the city hired the consulting firm to test if chemicals were

leaving the site.

“We’re all trying to get the same answers and get to the

bottoms of things,” he said. “I told them they need to come

prove to me that everything is fine, and I won’t be convinced

until they’ve done all the testing possible and show me the


EnviroForensics Chief Executive Steve Henshaw said the tests

results show that pollution wasn’t confined. “Clearly they

have not fully remediated or cleaned up the source,” he said.

The Environmental Protection Agency is expanding its

contamination testing area near the manufacturing facility,

The Daily Journal reported. The federal government has also

begun installing air-filtering systems in some residences.

Henshaw said the property’s technology is dated and ineffective.

“This is a classic example of a site that is put on autopilot and

seems to have fallen through the cracks,” he said. “As a result,

follow-up work wasn’t being checked and they assumed

the cleanup was working and it wasn’t.”

Co-op Program Teaches Students

Valuable Trade Skills By Ethan Forman

DANVERS, Mass. (AP) — Five years from now, a plumber will

be more important than an attorney.

That’s what Cranney Companies President Brian Cranney

joked last month, before a North Shore Chamber of Commerce

breakfast in Salem.

His point? There aren’t enough plumbers to go around.

Cranney said he doesn’t have enough workers to staff all of

the service trucks for his Danvers company, which provides

plumbing, heating, cooling and electrical services, among


But there’s a solution. Cranney has turned to Essex Tech’s

co-op program, to help train and recruit tomorrow’s plumbers,

electricians and HVAC technicians. His company is one

of several in the region that rely on the technical school for

future workers.

“It’s the main artery of my business on the North Shore and

how I’ve been able to grow it,” Cranney said. Many of the

leaders in his company today were first hired as high school

juniors. They went on to get their various licenses and work

for Cranney full-time.

Essex Tech’s co-op program places juniors and seniors with

businesses in various fields such as plumbing, electrical,

advanced manufacturing, culinary arts and construction, to

name a few.

“It’s the culmination of a student’s program, really,” said

Lisa Berube, Essex Tech’s cooperative education coordinator.

“They come here and they get the skills and the training to

be able to enter the workforce, so the cooperative education

program is that next piece, if you will, that gets them into

the workforce out of the school setting to apply those skills.”

The students work in a co-op job for one week, then take

high-school academic courses the following week, off and on

throughout the school year. They often earn more than the

minimum wage.

Culinary arts sophomore Emma Bedard, 15, of Salem, said

she is looking forward to joining the co-op program next

year. Bedard, who aspires to be a baker, was working at the

school’s Maple Street Bistro last month.

“I think it’s amazing because you can actually get the skills

and everything you need and it helps you get jobs going out

of high school,” she said.

“I think it’s pretty close experience to the real world,” said

sophomore Jack Donovan, 16, of Peabody, about what he’s

doing in the school’s advanced manufacturing shop. Donovan

said he had been thinking about a future in mechanical

engineering, but the skills he is learning now are closely


“I also like using my hands and getting dirty. It’s just such a

fun shop to learn in,” said Donovan, who plans to work in a

co-op job next year.

The demand to attend Essex Tech has skyrocketed.

The school has gone from under 1,200 students in 2014 to

1,421 students in 25 career and technical programs. Of the

1,200 applications it gets each year, it only has 375 slots.

The regional school is the result of a merger of the former

North Shore Tech, Essex Aggie and Peabody high school

vocational programs. While it opened several years ago,

Superintendent-Director Heidi Riccio, the guest speaker before

the North Shore Chamber last month, said the school is

already running out of space in some trade areas, including


Riccio said the school depends on business leaders like Cranney

to show the school what it needs to train its students.

“We also look at them as partners,” Riccio said. “They not

only hire our students, but we are also hoping to start an

adult education program to train existing workforce within

that industry, as well as future workforce.”

The construction trades are booming, and that means Essex

Tech co-op students are in demand, said Bonnie Carr, the

school’s community relations and partnership coordinator,

who also undertakes workforce development.

“The kids go out, they work. They (employers) keep them

through the summer. They work all of their senior year, and

then they pick them up after graduation,” Carr said.

Carr said there is a demand for students in culinary arts, given

Salem’s restaurant boom. There is also a demand for those

studying in health care fields. Last year, North Shore Medical

Center took six students who worked in various areas of the

hospital, including the emergency room.

“Our high school nursing students,” Riccio said, “were working

alongside physicians, emergency medical technicians,


Last month, Essex Tech’s plumbing shop was filled with the

sounds of banging as students worked on projects in tall,

plywood booths.

Riccio said the program has expanded to the point it ran out

of space for booths. So, the students built more.

Jim Russell, the grade 11 and grade 12 plumbing instructor, is

in charge of connecting students with North Shore plumbing

and heating companies. He said his students are in “huge”


“You know, the kids with the skills here you can’t get this

education even if you are an adult. This doesn’t exist,”

Russell said. “It only exists here, and with only 15 to 18 kids

per class, you know, they have skills that you can’t get at any

other place.

“They know how to do everything,” Russell said. “So, the

employers like that because they can train them the way

they want them but they have the basic, raw talent to work


Russell noted there is a shortage of plumbers. Their average

age in Massachusetts is 55. But the base wage of an experienced

union plumber is approximately $55 an hour, Russell

said. Benefits can boost this wage to more than $80 an hour.

“These kids are going to find themselves in a really good job

market,” said plumbing instructor Karl Jacobson. The connection

to local plumbing businesses through the co-op program

is vital. Many Essex Tech graduates stay with the company

they worked for in high school.

In the school’s advanced manufacturing shop, where future

machinists work on high-tech, precision manufacturing

lathes and mills, Riccio noted wages for machinists range

from $16 to $100 an hour. Some students are able to work

weekends making $30 to $40 an hour.

Instructor Jack Fraizer said from what the students are

learning, they can go right into a shop after they graduate.

And they are in demand, now, because many people stopped

going into the field when work moved overseas.

“We can’t even give them enough students because we don’t

have enough to give to them,” Fraizer said. “Right now the

demand for just certain companies I know of ... One just said

they need 300 people within the next year.”

Fan pumps at the Chicago Marriott Downtown

Magnificent Mile. The chiller system services the

hotel’s 970,000 sq. ft.

The Chicago Marriott Downtown Magnificent Mile hotel

occupies an enviable location along the city’s Magnificent

Mile, offering views of the surrounding city and Lake Michigan.

To help the 970,000-square-foot hotel retain its status

as a downtown destination for travelers, management is in

the process of completing a range of upgrades, including an

aesthetic facelift throughout its 1,200 rooms and suites.

Keeping pace with guest-facing enhancements, the hotel is

giving some much-needed attention to its major mechanical

systems — most recently with the installation of new chiller

equipment. As Marriott learned, choosing energy efficiency

equipment not only lowers operating costs but also can earn

incentives from the ComEd Energy Efficiency Program. Additionally,

the ComEd Energy Efficiency program offers a variety

of options, including direct incentives, to help customers

pay for these improvements.

Setting Sights on Improvements

For more than 40 years, the Chicago Marriott Downtown

Magnificent Mile had relied on its original mechanical equipment

to keep guests comfortable year round. In particular,

two 1,200-ton chillers worked in concert with a cooling tower

on the roof to keep the hotel’s guest rooms and suites air

conditioned during the hottest months of the year. Though

still functioning, that original equipment was struggling

to keep up with the demand. According to Ty Sanders, the

hotel’s director of engineering, the chillers were beyond the

end of their useful lives, and it was time to explore options

to bring the system up to date.

the chiller replacement at the Chicago Marriott

sustainable design, completed a master survey of the hotel.

“All the equipment was doing its best, but it was coming up

against age and efficiency problems,” said Eric Rosenberg, a

project manager at G/BA. “Reliability was always in the back

of everyone’s mind. Marriott didn’t want the equipment to

fail one day. So we helped them devise a plan for making


G/BA presented Marriott with a report summarizing the

condition of major equipment throughout the hotel and

suggested ways to move forward while saving energy and

money. The report provided a framework to help the hotel’s

ownership to weigh funding, capital planning and anticipated

operational disruptions that could play a role in project


While modernizing the hotel’s interior spaces, Marriott management

decided to replace the chillers during an upcoming

heating season. The upgrade process involved competitive

bidding among Chicago-area contractors. In the end, Marriott

selected Mechanical Incorporated as the project’s general


“We faced some highly-respected competition during this

process. I specifically put together a team for the build out of

this job, and since we’ve worked together for 25 years, it was

only right,” said Kirk Jurinek, a senior project manager at

Mechanical Incorporated. “We’ve probably installed 60 to 70

chillers, so I think that was refreshing to both Marriott and

Grumman/Butkus Associates.”

Bringing in Energy Efficiency

Once Mechanical Incorporated was chosen in 2017, construction

could begin. One of the first and most important decisions

made to improve energy efficiency was to downsize the

two existing 1,200-ton chillers and replace them with three

800-ton chillers.

Adding a third chiller gave Marriott greater flexibility of

temperature control throughout the property, and provided

redundancy in case a backup should be needed.

“They really only needed to run both chillers at full capacity

a couple days of the year,” said Rosenberg at G/BA. “But because

of the chiller size, even on a mild day, they might have

needed to use both of them. Smaller equipment allows for

greater flexibility in switching from one to another. It’s just a

better way to run the building without relying on two older

pieces of equipment.”

Jurinek’s team at Mechanical Incorporated designed a

three-dimensional building information model to show

exactly how the new equipment would fit into Marriott’s existing

layout. The model enabled contractors, engineers and

Marriott staff to envision the completed installation before

any equipment even arrived.

“The modeling really helped with the efficiency of the

installation,” Jurinek said. “Because Marriott’s engineers

know their building so well, they were able to offer helpful

logistical insight throughout the project.”

Construction began in October 2017 to coincide with the

hotel’s heating season. Marriott’s Sanders said this step minimized

any impacts on operations, as the hotel primarily runs

boilers during the colder months.

“We also had been under renovation for four years, so we

were used to cycling materials in and out of the building,”

he said.

Jurinek agreed that cooler outdoor temperatures made fall a

prime time to start the chiller replacement. However, he described

a few additional obstacles that crews worked around

to prevent any disruption to hotel guests and employees.

“The chillers are tucked below the hotel’s loading dock in

one of the least accessible parts of the building,” he said.

“Though the new chillers are smaller than the previous

equipment, they still had to be completely disassembled to

be brought in through the elevator shaft.”

To coordinate all the moving pieces, Mechanical Incorporated

oversaw the various trade professionals to complete

the installation on time and on schedule. Grumman Butkus

worked diligently to help Marriott secure thousands of

dollars in incentives through the ComEd Energy Efficiency


Negligible interruption to daily operations confirmed Marriott’s

decision to make this energy efficiency upgrade a

priority. The availability of incentives from ComEd made the

chiller replacement a no-brainer.

“The rebates were a nice bonus to move the project forward,”

said Sanders. “They made the approval process go


Marriott received over $200,000 in incentives for its chiller

replacement project because the team chose qualifying

high-efficiency equipment.

“The ComEd program is particularly nice because it has

prescriptive options where you can almost check the box. If

you install this piece of equipment, you’ll get this incentive

amount,” Rosenberg said.

Everything from high-efficiency heating and cooling equipment

to LED lighting and variable frequency drives for motors

and fans can qualify for incentives.

“And the utility also offers custom options if you’re doing

something a little more involved,” Rosenberg added. “If you

have an idea that reduces electricity use, the custom program

is there to provide incentives to move the project forward.”

ComEd’s custom incentives are based on the actual kilowatt-hour

savings achieved by a project in the first year after

it is completed. Qualifying projects can earn incentives up to

$0.07 per kWh saved in the first year.

“It’s a great way to get people to think beyond the cheapest

approach,” said Rosenberg. “With greater energy efficiency

and better products moving forward, customers can save

even more on energy costs over time.”

Recognizing Multiple Benefits

Following a seamless approval and installation process, Sanders

said the hotel has achieved numerous benefits from the

new cooling equipment.

“Our energy savings from the chillers add up to approximately

$100,000 per year,” he said. “Our guests and employees

are more comfortable. From a maintenance perspective,

we’ve received fewer service calls, and the new equipment

allows us to operate more efficiently during periods between

the heating and cooling seasons.”

The addition of the third chiller also gives Marriott more

flexibility to control the temperature in spaces across the

hotel. “With the old equipment, if they had to shut down

one chiller during the summer, they could run into issues,”

Jurinek said. “Now they have the luxury of energy savings,

with greater options for operations and maintenance.”

Investments in energy efficiency also can yield benefits that

last for years to come. “People used to look at their energy

bills and say, ‘We’ve got to do something to lower them,’”

Rosenberg added. “Now, many people think beyond that

and try to make things better not only for themselves, but

also for future generations. There is a nice ripple effect with

reduced energy consumption.”

Building for the Future

Sanders described Marriott’s chiller replacement project as a

complete success and encourages other businesses to pursue

energy-saving options. “Not only will these upgrades help

preserve our natural resources, but the cost savings are an

immediate benefit to our ownership,” he said.

Rosenberg applauds Marriott’s leadership and approach in

replacing outdated equipment before experiencing major

issues from a failed system. He advises other businesses to

take a similar route.

“If you can plan for upgrades and get started before it

becomes an urgent need, you’ll be able to find the best longterm

solutions for your business,” Rosenberg said. “With

incentives offered through the ComEd Energy Efficiency

Program, you can save even more on the upfront cost. Now is

a great time to invest in improving your energy efficiency.”

Michigan Officials Urge Bridge

Authority to OK Pipeline Deal By John Flesher

TRAVERSE CITY, Mich. (AP) — Michigan officials took another

step Nov. 8 toward construction of an oil pipeline tunnel

beneath the channel that links Lakes Huron and Michigan

by asking the Mackinac Bridge Authority to accept oversight

responsibility for the proposed structure.

Department of Natural Resources Director Keith Creagh and

two consultants pitched the plan to the bridge authority.

No vote was taken but the authority heard dozens of public

comments, most opposed to the project as potentially posing

a risk to the Straits of Mackinac and the area’s fishing and

tourism industries.

“Don’t ram this down our throats. Don’t rush things,” said

Bay Mills Indian Community chairman Bryan Newland, who

added that the project would violate native fishing treaty


Gov. Rick Snyder’s administration reached a deal last month

with Enbridge Inc. to drill the tunnel beneath the Straits of

Mackinac over 7 to 10 years at a cost of up to $500 million,

which the company would pay. The bridge authority would

assume ownership after completion and lease the tunnel

back to Enbridge for 99 years.

It would replace an underwater segment of Enbridge’s Line

5, which carries about 23 million gallons of oil and natural

gas liquids daily. Environmentalists are pushing to decommission

the twin lines, which have been in place since 1953,

while the company says they’re in good condition.

A crucial part of Snyder’s plan is putting the bridge authority

in charge of the tunnel, even though the authority’s only responsibility

since its founding has been managing the 5-milelong

bridge linking Michigan’s Upper and Lower Peninsulas.

Michael Mooney, a Colorado School of Mines expert on

tunnel design and consultant for the state, said the tunnel

proposal is sound and would provide extra protection by

encasing the new pipeline in concrete.

“There is virtually no way for product to leak out of this

Wind Towers Coming Down Under

Court Orders

FAIRBANK, Iowa (AP) — Developers are taking down three

northeast Iowa wind turbine towers under court orders.

The first was removed last week and the second is going

down this week, the Waterloo-Cedar Falls Courier reported.

The 450-foot-tall (137 meters) towers were erected in 2015

just east of Fairbank in Fayette County. They drew opposition

from housing developers and neighboring homeowners who

believed the towers would be detrimental to the city.

Fairbank City Council members filed a lawsuit that said the

county issued construction permits without following zoning

ordinances. Woods Construction, which had been developing

a residential subdivision near the wind farm, filed a separate


A judge sided with the city in 2016, and the Iowa Supreme

Court upheld that ruling. The turbines must be removed by

Dec. 9.

Resident Joyce Kerns said she’s happy with the decision to

remove the turbines.

“I’m thrilled,” Kerns said. “The constant whoosh, whoosh,

whoosh sound they make is nonstop, and the shadow effect

was like I was back in the ’70s with the disco strobe light.”

The developers — Mason Wind, Dante Wind 6, Galileo Wind

1 and Venus Wind 4 — are still appealing in the courts. The

companies requested a variance from the Fayette County

Board of Adjustment to allow the turbines to remain. The

companies are appealing the board’s June decision to deny

the request.

“While we continue to seek other avenues to allow those investments

in wind energy to remain in Fayette County, until

we get a different ruling the wind LLCs will continue to fully

comply with the order currently in effect,” said Bret Dublinske,

an attorney for the companies.

Mortenson Completes Enclosure of

Halas Hall Addition for NFL’s Chicago


The current project follows the 2013 Halas Hall renovation

led by Mortenson that upgraded the Bears’ business offices

and added a state-of-the art media and broadcast center,

viewing suite and cafeteria. One of the top three national

sports builders, Mortenson has completed more than $8

billion in professional and college sports facilities in the past


“We want to use every advantage to help our players and

coaches succeed, and a first-class training and recovery center

is key to our team development plan,” said Bears President

and CEO Ted Phillips. “Mortenson has worked closely

with us to complete the expansion and remodeling of Halas

Hall as quickly as possible, even as the team and business

office staff continue using the building.”

Mortenson is on track to complete its expansion and renovation of Halas

Hall before the start of next year’s football season.

Chicago — Mortenson has completed the enclosure of the

major new addition to Halas Hall, putting it on track to complete

the expansion and renovation of the home of the Chicago

Bears National League Football team before the start

of next year’s football season. The modernization, including

the 162,500 square foot addition that more than doubles

the size of the Bears’ headquarters, will deliver an expansive,

state-of-the-art training center for players, coaches and the

entire football operation.

“The Chicago Bears are investing for now and the future

with this world-class facility. The Bears are providing all of

the tools, equipment, technology and amenities to help its

players and coaches prepare and perform at their best,” said

Lori Leber, Mortenson design phase executive who is overseeing

the project.

Improvements include:

• 13,000 square foot indoor turf field with projection screen,

virtual reality room and adjacent classrooms for learning

and practicing plays

• Expanding the weight room by 2,000 square feet

• Doubling the size of the equipment room, recovery space,

and nutrition and fuel station

• Building new locker rooms, players lounge

• Expanding coaches’ offices, position meeting rooms, and

draft room

• Increasing by four times the hydrotherapy and sports medicine


Meeting the ambitious construction schedule while the

building is occupied requires careful staging and coordination

of work supported by innovative Lean construction

techniques. The Bears organization brought in Mortenson

from the start, so the builder could play a key role in informing

the building plan, design and layout. Mortenson

worked with the design team and the Bears to optimize the

floor plan so that it would provide the least disruption to the

Bears’ ongoing operations. For example, Mortenson advised

on the ideal location for the demolition of the north addition

to occur. This allowed for optimal construction phasing

which made it possible for the Bears to remain in their

existing locker room until the first phase of construction was

completed. Mortenson also used prefabricated wall panels

to reduce installation time, enabling the team to meet the

accelerated construction schedule.

Mortenson and its subcontractors are using the Lean approaches

of 5S and Pull Planning to increase productivity

and safety. 5S, which stands for sort, straighten, shine,

standardize and sustain, makes construction sites cleaner and

more efficient. With Pull Planning, Mortenson and its trade

partners collectively determine the best work sequences and

durations, identify conflicts and develop solutions. These

strategies are especially effective at the Lake Forest, Ill. site,

where the team has minimal space onsite to stage and store

materials and must rely on just-in-time deliveries.

Mortenson broke ground on the addition in March.

Sioux Falls Manages Contaminated

Water From Toxic Foam

SIOUX FALLS, S.D. (AP) — Sioux Falls officials are grappling

with well shutdowns as the extent of the city’s water contamination

from decades of firefighting foam use remains


Sioux Falls currently has 19 municipal wells sitting dormant

in the aftermath of innumerable gallons of toxic firefighting

foam that contaminated the grounds of the city airport nearly

50 years ago, the Rapid City Journal reported. Chemicals

linked to cancer and other health issues were found to have

contaminated 15 municipal wells, including 10 that have

concentrations above what the Environmental Protection

Agency deems safe.

About 28 percent of the city’s water production from the Big

Sioux aquifer is shut down.

The South Dakota Air National Guard and the Sioux Falls

Fire Department both used the toxic firefighting foam for

many years near the airport, which led to the contamination

of the city’s drinking water. But the scope of the issue is still


“We really haven’t determined the extent of release yet,”

said Capt. Jessica Bak, a public affairs officer with the Air

Guard at the Sioux Falls Regional Airport.

In 2013, the city’s water purification plant found chemicals

from firefighting foam, known as per and polyfluoroalkyl

substances (PFAS), at levels below the EPA’s health advisory

level. The level of exposure beneath the EPA’s threshold

means there aren’t expected adverse health risks.

The city responded to the findings by testing all municipal

wells to identify the source and shutting down every well

where the chemicals were found.

City engineer Tim Stefanich, who oversees the water system,

acknowledged that “there was a little bit of time between”

finding the contamination, determining its source and deciding

to shut off wells. But he said that there was minimal fear

of an immediate health risk with the low levels of exposure.

The city tested for PFAS again in 2014 as part of an EPA-mandated

water sampling program, but didn’t detect any of the

chemicals. The city tested again in 2016, when some low

levels were found.

The city shut off more wells, leading to the 19 wells offline

today. Water leaving the city’s purification plant is now

sampled monthly, and no water samples have contained the

chemicals since 2016.

Stefanich and Trent Lubbers, the city’s utilities operation

administrator, believe the contaminated water situation is

under control.

The city has been purchasing water from the Lewis and Clark

Regional Water system, a nonprofit, wholesale provider of

treated water. But Sioux Falls will likely need a more sustainable


“They have the short term kind of covered,” said Mark

Meyer, drinking water program administrator for the state’s

Apple Offers Range of iPhones, From

$450 to $1,100New Mobile App

Plus, and the iPhone XR in New York. The new XR phone has a larger display

NEW YORK (AP) — Apple’s new iPhone XR has most of the

features found in the top-of-the-line iPhone XS Max, but not

its $1,100 price tag. The XR offers the right trade-offs for just


For something cheaper, you’ll need to look in the iPhone history

bin. Older models are still quite good. If you’re shopping

for a new phone, it pays to think hard about what you really

want and what you’re willing to pay for it. Improvements

over the previous generation tend to be incremental, but can

add up over time — and so do the sums you’ll pay for them.

iPHONE 7 ($449)

The big jump in iPhone cameras came a generation earlier

with the iPhone 6S, when Apple went from 8 megapixels to

12 megapixels in resolution. With the iPhone 7, the front

camera goes from 5 megapixels to 7 megapixels, so selfies

don’t feel as inferior.

The iPhone 7 is Apple’s first to lose the standard headphone

jack. Headphones go into its Lightning port, which is used

for both charging and data transfer. It’s a pain when you

want to listen to music while recharging the phone. For that,

you need $159 wireless earphones called AirPods. Apple no

longer includes an adapter for standard headphones; one

will set you back $9 if you need it.

iPHONE 7 Plus ($569)

This larger version of the iPhone 7 has a second camera lens

in the back, allowing for twice the magnification without

any degradation in image quality. It also lets the camera

gauge depth and blur backgrounds in portrait shots,

something once limited to full-featured SLR cameras. The

dual-lens camera alone is a good reason to go for a Plus,

though the larger size isn’t a good fit for those with small

hands or small pockets.

iPHONE 8 ($599)

New color filters in the camera produce truer and richer colors,

while a new flash technique tries to light the foreground

and background more evenly. Differences are subtle, though.

The year-old model, similar in size to the iPhone 7, restores a

glass back found in the earliest iPhones. That’s done so you

can charge it on a wireless-charging mat, which also solves

the problem of listening to music while charging. But with

more glass, it’s even more important to get a case and perhaps

a service plan.

iPHONE 8 Plus ($699)

Again, the Plus version has a larger screen and a second lens.

For those shots with blurred backgrounds, a new feature lets

you add filters to mimic studio and other lighting conditions.

iPHONE XR ($749)

The display on Apple’s latest model, which comes out Friday,

lacks the vivid colors, contrast quality and resolution of

the pricier iPhone XS and XS Max. As with the XS models,

though, you’ll still get a display that largely runs from edge

to edge. Gone is most of the surrounding bezel along with

the home button. Many tasks now require swipes rather

than presses. The fingerprint ID sensor is replaced with facial

recognition to unlock the phone. There’s more display than

the regular XS, but the phone itself is also larger — just not

as large as the Max.

The camera continues to improve, with better focus and

low-light capabilities. Many shots now blend four exposures

rather than two for better lighting balance in suboptimal

conditions. The XR doesn’t have the dual-lens camera,

though it can offer some of the blurred-background effect

with software.

iPHONE XS ($999)

As with the iPhone X it replaces, the new XS also has an

edge-to-edge display. The display has about the same surface

area as the iPhone 7 Plus and 8 Plus, while the phone

itself is only slightly larger than the regular iPhone 7 and 8.

Improved display technology means vivid colors and better

contrasts, including black that is black rather than simply

dark. You also get a dual-lens camera.

iPHONE XS Max ($1,099)

This is essentially the “Plus” version of the iPhone XS. The

phone itself is about the size of the Plus, but with more room

for the display. This phone won’t feel big for existing Plus users,

but think twice if you have small hands or small pockets.

While Supplies Last

Apple no longer sells the iPhone SE, which is essentially a

three-year-old iPhone 6S, packed in a body that’s smaller but

thicker than the iPhone 7 and 8. Though the trend in phones

has been to go bigger, some people preferred the smaller

size — and the $350 price tag. You can try to get it from

some wireless carriers and other retailers, at least for now.

All in the Memory

If you get an SE, 7 or 7 Plus, consider spending another $100

to quadruple the storage. Those phones come with a paltry

32 gigabytes, just half of what’s standard these days. If you

don’t upgrade, you risk filling up your phone quickly with

photos, video, songs and podcasts.

Can a Holographic Screen Help a New

Phone Break Out? By Anick Jesdanun

NEW YORK (AP) — Most leading phones offer the same

basics: Big screens, decent battery life and good cameras. So

when a newcomer brings something innovative to the party,

why is it difficult to break through a phone market dominated

by Apple and Samsung?

One such smartphone was released Nov. 2 from Red, a

company with roots in digital cameras for movie productions.

The new Hydrogen One has a holographic screen that

produces 3D visuals without needing special glasses. It is

launching with two major movies converted to this format

and allows users to create and share their own videos shot

with the phone.

Red’s goals are modest — about 16 million units a year,

based on Red’s stated target of 0.5 percent of Samsung’s

sales. But Red will need customers beyond the tech elite

and camera buffs; it’ll need their friends and friends of their

friends. It doesn’t help that the Hydrogen One carries a hefty

$1,295 price tag.

“The Red Hydrogen One stands little chance of upsetting the

smartphone status quo,” said Geoff Blaber, a research analyst

at CCS Insight.

Chipping away at Apple’s and Samsung’s dominance is much

harder than it used to be because phone innovation isn’t so

much about hardware any more, Creative Strategies analyst

Carolina Milanesi said. What matters more, she said, is the

software and artificial intelligence behind it.

Consider Apple’s new iPhones. Sure, the new XR and XS models

all have decent screens, battery life and cameras. But Apple

has also been emphasizing such software-based features

as augmented reality, artificial intelligence and automation

using the Siri digital assistant. Or take Samsung’s Galaxy Note

9. Signature features include the use of AI to automatically

fine-tune images.

While the Hydrogen One’s screen is different, Milanesi said,

it’s not necessarily something the mass market will gravitate

Red founder Jim Jannard said his phone is about making

waves in a sea of smartphone sameness.

“We don’t buy the same make, model or color of car that

our next-door neighbor has,” he said. “It’s important to keep

this industry pushing along ... and give people some new

choice. What we’ve done is pretty nuts.”

The phone started selling Nov. 2 through AT&T and Verizon

in the U.S.

Red calls the screen technology 4V, for four view, which is

another way of saying it’s doubling what twin-lens 3D cameras

produce by adding depth data to each image. There’s

a special material under the screen that lets 4V photos and

video appear to the viewer in 3D. Images that aren’t shot or

converted to this format will look the same as they do on any

other screen. Attempts to photograph a 4V screen will also

produce images that don’t look any different.

Yet the 3D wizardry indeed works, though it’s more pronounced

in some scenes than others. Images of a soccer goalie

blocking a shot feels realistic, but a waterfall at Yosemite

National Park looks like video taken with a regular camera

(though leaves in the foreground looked 3D). The Red phone

might remind you of holographic stickers in which the view

shifts slightly as you tilt them.

The Warner Bros. studio is giving customers of parent company

AT&T two free 4V movies: the first Harry Potter prequel,

Fantastic Beasts and Where to Find Them, and Steven

Spielberg’s Ready Player One, which is set in a virtual world.

The studio plans to convert about a half-dozen other movies

initially. Red will have tools for producers to convert existing

3D video into the 4V format.

The Hydrogen One also has twin lenses in the back to capture

4V photos and video. Trouble is, people you share them

with will get a normal image unless they also have a Hydrogen


The phone also has a handful of 4V games.

Red’s 4V could run into the same problems that virtual reality

has faced. People haven’t been rushing out for headsets,

while video creators haven’t been rushing out to make VR

experiences. There’s a chicken-and-egg problem at play.

Beyond the fancy screen, the phone is thick at a time Apple

and Samsung make thinner phones. That’s done to fit in

a bigger battery, with 12 percent more capacity than the

super-charged Note 9. The sides have ridges to improve the

grip. The phone has pins for expansion modules, such as

an adapter for any standard SLR lens. (Incidentally, a major

manufacturer that tried this modularization approach, LG,

backed away from it after a year.)

Jannard has a history of disrupting other industries, too. He

previously founded Oakley, which became a force in sunglasses

using many of the word-of-mouth techniques he is

hoping to replicate with the new phone.

“We’re not trying to win over the whole world,” he said.

“We’re trying to provide a phone that we hope enough

people like. Otherwise, I’m going to own the single most

expensive cellphone in the world, and I’m happy with that.”

RectorSeal Introduces Smart Water Leak

Monitoring, Detection and Prevention System

RectorSeal® LLC, Houston, a leading manufacturer of quality

plumbing and HVAC/R products, introduces TripleGuard,

a smart electronic water leak monitoring, detection and

prevention system product line that guards against property

damaging, infrastructure water source leaks in residential

and commercial real estate.

Available through North American plumbing and HVAC/R

wholesalers, TripleGuard is ideal for any real estate owner

or manager overseeing property with dish washers, clothes

washers, sinks, hot water heaters, hydronic/plumbing piping

and other potential water leak sources.

TripleGuard consists of two products that are maintenance-free

and installable in less than an hour: 1) the Triple-

Guard Smart for Cloud-based monitored facility leak protection;

and 2) the TripleGuard Active appliance lead shutoff,

designed mainly for single-source protection such as water


While the plumbing industry currently has many leak detectors,

few brands actually proactively stop water flow and

subsequent property damage while also enabling the user

with cloud-based control remotely or onsite via smartphones

or the Internet. “Statistics reveal North American water

damage insurance claims total billions of dollars annually

and 250-gallons (946-liters) of water can potentially leak

daily from just an 1/8-inch (3-mm) crack in a pipe,” said Brian

Ilagan, TripleGuard senior product manager.

The TripleGuard Smart system includes:

• Actuator shutoff unit for the supply water line. The actuator

is a high-torque design that fits over a 3/4, 1, or 1-1/4-

inch (228, 305, 381-mm) ball valve (sold separately) on a

building or zone’s primary water supply piping. It operates

wireless with 4 AA batteries. The actuator is designed

to withstand fully-submersed natural flooding situations

and in temperature extremes from -4°F to 124°F (-20°C

to 51°C) temperatures The actuator automatically closes

and opens the ball valve monthly to proactively prevent

scale buildup, thus requiring no maintenance other than

battery replacement every four years;

• Two water leak detectors. The sensors require two

AA-batteries and placement under a potential water leak

source. Maintenance requires battery change out every

two years;

• A Cloud-connected HUB. A 915-Mhz wireless device

connects to the Cloud via Wi-Fi or a hard-wired modem

Ethernet connection. The smart device accepts wireless

communications from the sensors, and then monitors sensor

status (scalable up to 30 sensors/HUB). When a sensor

detects water, the HUB receives the communication and

then wirelessly signals the actuator to close. HUB maintains

a historical record of sensors for troubleshooting

and status reports.

• A smartphone app. The app allows remote access to the

HUB for monitoring and controlling operation. The app

can also be used to manually shutdown the building or

HUB zone water supply remotely when unoccupied.

The TripleGuard Active is a one-piece actuator valve that

monitors and detects water heater leaks. Its single 10-footlong

(3-meter), umbilical cord-connected sensor placed in the

water heater pan automatically deactivates the cold water

shutoff valve when detecting a water leak presence. “Statistics

reports that 75-percent of water heaters fail within 12

years and cause property damage,” added Ilagan.

The TripleGuard product line’s other features include:

One-year product warranty;

• Valve is NSF/ANSI Standard 61 (NSF-61) and NSF-372 certified

for potable water;

• Multiple kits can be observed simultaneously on a manifest

monitoring system for Home Owner Associations

(HOA), multi-family housing management departments,

and other overseers of large facilities with multiple units:

• Potential for reducing property insurance premiums and

satisfying insurers’ water leak policy provisions;

• Future generations will integrate with Internet of Things

(IoT) platforms;

Danfoss Variable-Speed Compressors

With IDV Create Efficiency Opportunities

Danfoss has added new 8.5-ton and 11-ton* variable-speed

compressors with intermediate discharge valves to its popular

VZH range, giving commercial cooling manufacturers the

market’s most complete choice of variable-speed scrolls with

qualified drives.

The new inverter scrolls are ideal for data center close

controls and rooftop units, enabling precise, energy-efficient

cooling. These compressors are also an excellent fit for

rooftop units, helping OEMs meet challenging new seasonal

and part-load efficiency standards, like the US Department

of Energy’s (DOE) energy conservation regulations beginning

in 2023. Likewise, for chillers, the Danfoss VZH range will

enable OEMs develop a competitive range of systems capable

of exceeding the demanding Ecodesign Lot 21 targets coming

into effect in 2021.

According to Luigi Zamana, senior marketing director for

Danfoss Commercial Compressors, “The extended VZH range

gives OEMs the opportunity to work with a single, proven

supplier of prequalified variable-speed compressor and drive

Cooling manufacturers are therefore under pressure to improve

part-load efficiency in order to satisfy DOE regulations

and continue to sell units in major world markets. With their

ability to continuously modulate capacity, variable-speed

compressors are a key part of meeting this challenge.

Danfoss VZH scrolls go even further. They feature intermediate

discharge valves (IDVs), which prevent over-compression

losses that compromise efficiency in standard scroll technology

under part-load conditions. The result is a significant

improvement in integrated efficiency scores. Efficiency is

further improved with state-of-the-art permanent magnet

motors that help reduce power consumption under all operating


Tailor-Made for Rooftop Units and IT Close Controls

Energy efficiency is particularly important in data center

cooling applications. With round-the-clock cooling demand,

each incremental reduction in power consumption has a

large impact on energy bills, giving IDVs a clear advantage in

making data centers more sustainable as IDVs deliver much

higher system efficiency for the same cooling capacity, especially

at very high evaporating temperatures (low pressure

ratios) that are typical of data centers.

But servers also need precise conditions to function reliably,

and variable-speed technology gives the unparalleled ability

to achieve a narrow, 0.54 °F (0.3 °C) temperature window,

without sacrificing power usage effectiveness (PUE).

Additionally, the VZH’s extended operating map and ability

to work in a wide range of conditions, makes it an obvious

choice for IT close control systems, as well as rooftop units in

markets where seasonal efficiency is a priority.

Prequalified Packages Accelerate Time to Market

Danfoss is able to supply properly-sized compressors and

drives as a matched, prequalified and certified package. This

ability dramatically accelerates the development process,

allowing OEMs to bring new, more efficient units to market


A Road Map to Lower GWP

Currently, VZH compressors are approved for use with

R-410A, a refrigerant with a Global Warming Potential

(GWP) of less than 2500. Danfoss’ commitment to lower-GWP

alternatives — including its new, 3000-m2 testing facility for

flammable refrigerants — means we have spelled out a clear

road map for a safe, managed transition before refrigerant

phase-downs commence in earnest.

Variable-Speed With IDVs: the Key to SEER, IPLV and IEER

Worldwide, energy-efficiency standards are increasingly

based on seasonal efficiency measures like the Seasonal Energy

Efficiency Ratio (SEER), Integrated Energy Efficiency Ratio

(IEER), and Integrated Part Load Value (IPLV). These standards

are designed to better reflect actual load profiles.

ATLANTA — ASHRAE has announced that an agreement has

been reached with the Indoor Air Quality Association (IAQA)

for IAQA to transition to an association management firm.

IAQA became an affiliate of ASHRAE in 2015. In that relationship,

IAQA’s operational base became integrated within

ASHRAE’s headquarters operations in Atlanta, Ga. With this

change, IAQA will take on a more independent management

position. Both organizations are committed to continue collaborative

programming that benefits all members involved.

“ASHRAE has progressed strongly as a global society and

our focus now turns to positioning each organization for

long-term growth and leadership,” says 2018-19 ASHRAE

President Sheila J. Hayter. “The best way to accelerate that

transformation is by separating our associations to uniquely

position both ASHRAE and IAQA to lead their markets, while

focusing strongly on the needs of our members.”

During its affiliation, IAQA operated independently within

ASHRAE’s organizational structure, maintaining its own

brand and Board of Directors. Both associations viewed the

initial partnership as an asset for the growth and development

of each organization’s distinct membership base.

“This change comes as a necessity to ensure the growth,

expansion and financial stability of our membership and

association,” says IAQA President Jay M. Stake. “IAQA will

now be managed by AH, an association management company

(AMC) with offices in Mount Laurel, N.J. and suburban

Washington, D.C.

IAQA will continue to offer corporate and individual memberships,

education, conference and resources to indoor air

quality professionals. ASHRAE will continue its longstanding

leadership of IAQ sciences and technologies.

A task force has been established to examine the best path

forward for both organizations.

ASHRAE Seeks Third

Round of Comments on

Legionella Guideline 12

ATLANTA (Nov. 2, 2018) – ASHRAE is seeking a third round of

public comments on ASHRAE Guideline 12- 2000R, Proposed

Revision of Guideline 12-2000, Managing the Risk of Legionellosis

Associated with Building Water Systems. Guideline 12

is open for a 45-day public review until Dec. 17. Those interested

in reviewing and commenting on the guideline can do

so through the ASHRAE Online Comment Database. In this

Independent Substantive Change (ISC) public review draft,

only revisions in strikethrough and underlined are open for


The purpose of ASHRAE Guideline 12 is to provide information

and guidance to assist in control of legionellosis associated

with building water systems. It also provides guidance

useful in the implementation of ASHRAE Standard 188, “Legionellosis:

Risk Management for Building Water Systems.”

ASHRAE Guideline 12 is intended for use by owners of

human-occupied buildings and those involved in the design,

construction, installation, commissioning, management,

operation, maintenance, and service of centralized building

water systems and components.

“This guideline addresses an important issue that impacts

public health and safety, so feedback is critical,” said Paul

Lindahl, committee chair for ASHRAE Standing Standard

Project Committee (SSPC) 188, the committee responsible for

writing Guideline 12. “Guideline 12 will be a strong companion

to ASHRAE Standard 188 in an effort to provide building

owners with the resources needed to reduce the risk of

Legionellosis and save lives.”

The Centers for Disease Control and Prevention estimates

there are between 8,000 and 18,000 cases of Legionnaires’

disease in the United States each year, with more than 10

percent of the cases fatal. Most are the result of exposure to

Legionella associated with building water systems.

1930s Hollywood Theater in Fort Worth

Needs Pricey Face-Lift By Bud Kennedy | Fort Worth Star-Telegram

Downtown Fort Worth’s hidden Hollywood Theater has been closed for around 40 years. Only an awning outside the Historic Electric Building Apartments

hints that the mezzanine lobby, balcony and ornate auditorium of a 1,800-seat theater are hidden behind locked doors. (Steve Wilson/Star-Telegram via


FORT WORTH, Texas (AP) — Dark 41 years, a forgotten downtown

movie theater flickered to life the other day, and for a

few minutes Fort Worth relived the era of downtown glitz,

showbiz premieres and Gone With the Wind.

The Fort Worth Star-Telegram reports the 1930-vintage Hollywood

Theater, sealed away for decades like some old movie

monster’s secret crypt, opened to daylight for the first time

in two generations as a crowd relived past grandeur and

imagined a future restoration.

Only an awning outside the Historic Electric Building Apartments

hints that the mezzanine lobby, balcony and ornate

auditorium of a 1,800-seat theater are hidden behind locked

doors at 410 W. Seventh St.

“I love old Fort Worth things,” said Casey Tibbetts, 36, president

at the new Guaranty Bank & Trust location next door.

He saw the theater and arranged public tours as part of the

new bank’s open house.

“When we picked this location, people started asking about

the theater. We wanted people to come take a look.”

Like an aging movie star, the Hollywood needs an expensive


Restoring a typical theater costs from $5 million to $10 million,

according to the National Trust for Historic Preservation.

The lower auditorium floor and seats are gone, stripped and

removed to make room for residents of the adjacent apartments

to park underneath.

But the balcony, walls, ceiling and screen area remain, along

with the mezzanine, marble staircase and part of the lobby,

in a style described in one opening-day 1930 news report as

Georgian modernist.

Houston-based owner Tradewind Properties has been

advertising the 3,000-square-foot lobby and concourse and

12,000-square-foot theater for lease.

“I personally think it sets up nicely for a performance venue,”

said Andy Taft, president of Downtown Fort Worth, Inc.

“I was surprised at how intact the features are inside. It

doesn’t take much imagination to see the potential.”

It’d need disability access and an auditorium floor. But it

could easily become a black-box performance theater or

music club.

The Hollywood is inside the Electric Building, built in 1929 by

Houston investor Jesse H. Jones for Texas Electric Service Co.,

now TXU Energy.

The Historic Star-Telegram Building, converted in 2013 to

MorningStar Partners, is next door. (The Star-Telegram is now

in a different Jesse Jones tower at 808 Throckmorton St.,

built in 1930 as the Fair Building.)

The Hollywood was built in 1930, just when the industry

was switching from silent movies and musicians to “talking

pictures,” so it only has a screen, not a stage. The first movie

shown was director Frank Capra’s “Flight.”

In 1940, the Hollywood was in the spotlight twice.

In February, it unreeled Fort Worth’s first-run showings of

“Gone With the Wind,” to audiences that included Civil War

veterans and that stood in lines circling the block.

That September, the Hollywood and the larger Worth Theater

one block east co-hosted the city’s first world movie

premiere: “The Westerner” with Gary Cooper, telling the

story of legendary Texas frontier Judge Roy Bean.

The movie was partly shot at Star-Telegram owner Amon G.

Carter’s Shady Oak Ranch. A Houston movie critic described

the premiere, hosted by comedian Bob Hope, as classic Fort


“Cowboys in full regalia slouched around in boots, cowboy

Stetsons at rakish angles.

The dinner out at Amon G. Carter’s ranch looked like a

miniature Academy Awards banquet. In cowboy outfit and

riding his Palomino pony, he greeted the celebrities. ‘I can

think of nothing more appropriate than having the premiere

here where the West begins,’ he said.”

It was the night Hollywood came to the Hollywood.
